Symmetry resolved entanglement in Lifshitz field theories
M. Reza Mohammadi Mozaffar, Ali Mollabashi
We investigate symmetry-resolved entanglement in non-relativistic quantum field theories, including complex Lifshitz scalar chains and Lifshitz fermionic models. Using charged mome…
Scrambling Without Chaos in Random Free-Fermionic Systems
Ali Mollabashi, Mohammad-Javad Vasli
We study the role of randomness in the scrambling of quantum information within integrable free-fermionic systems. Considering quadratic Hamiltonians with varying degrees of random…
Information Scrambling in Bosonic Gaussian Dynamics
Ali Mollabashi, Saleh Rahimi-Keshari
We investigate the dynamics of information scrambling in bosonic systems undergoing Gaussian unitary evolution associated with quadratic Hamiltonians. For initial Gaussian states,…
Multi-entropy and the Dihedral Measures at Quantum Critical Points
Jonathan Harper, Ali Mollabashi, Tadashi Takayanagi +1
The multi-entropy and dihedral measures are a class of tractable measures for multi-partite entanglement, which are labeled by the Rényi index (or replica number) as in the RÅ
